Auricular cartilage regeneration using chondroitin sulfate-based hydrogel with mesenchymal stem cells in rabbits.

We successfully fabricated a scaffold composed of alginate, gelatin, and chondroitin sulfate. This scaffold was further enhanced by the incorporation of Wharton's jelly mesenchymal stem cells. Our findings demonstrate that this composite scaffold has remarkable biocompatibility and mechanical characteristics. The present study successfully demonstrated the therapeutic potential of the SA-Gel-CS hydrogel containing WJ-MSCs for cartilage regeneration in rabbits.
